Allegheny County likely will see millions of dollars in new revenue when a casino starts operating in Pittsburgh as soon as next year, and two County Council members want that money to go exclusively toward reducing property taxes and government debt.

Jan Rea and Eileen Watt, both Republicans, will introduce legislation at tonight's meeting that lays out requirements for the use of gambling money.

"I think one of the most important things right now is property tax relief," said Ms. Watt, of Cheswick.

Under a law passed by the state Legislature in July 2004, both the county and the city of Pittsburgh will receive 2 percent of gross revenue from one stand-alone slot machine parlor.

Ms. Rea and Ms. Watt put forward their proposal soon after the state law was passed, but their bill later died in committee.

Council President Rich Fitzgerald, D-Squirrel Hill, said the issue will take on added importance this year, as the state Gaming Control Board considers applications from three major competitors for the city's lone casino license.

The board is expected to award a license by early next year.

"I think now that we're getting close it makes sense to look at their plan," Mr. Fitzgerald said of Ms. Rea and Ms. Watt's proposal. But he also is willing to consider others.

Councilman Dave Fawcett, R-Oakmont, has suggested using some of the slots money for riverfront trails.

County Chief Executive Dan Onorato supports using the money to lower property taxes, according to his spokesman, Kevin Evanto.

"When and if the slots money starts to come in, it's earmarked for the county general fund," Mr. Onorato said. "That will enable us to lower property taxes."
